PNEUMATIC BELL-RINGING APPARATUS.

. "SPECIFICATION forming part of Letters Patent No. 2 845,311, datedSeptember 4, 1883;

Application filed June 6, 1883.

(No model.) Patented in Germany December 2?, 1881, No. 18,546, and May9, 1882, No. 20,618, and

in Austria-Hungary October 27, 1882.

T aZZ whom, it may concern Be it known that I, ROBERT LATOWSKI, asubject of the King of Prussia, residing at jOels, Silesia, Prussia,Germany, have invented 5 certain new and useful Improvements inBel1-Ringing Apparatus, a specification. 7

My invention relates to bell-ringing appa ratus actuated by steam, air,or gas, and has of which the following is 1 10 for its object toovercome the difficulties con- 40 of an apparatus with 45. slightmodifications. a. Similar letters represent similar parts in all thefigures. I I

c is the collecting-vessel, I and b the pipe for W admitting steam, gas,or air into the same; a, 50 the valve through 1 nected hitherto with thelubricating and keeping in order the usual steam ringingapparatus.

. When steam, gas, or air of a'certain pressure 1 is escaping out of avessel through an aperture provided with a valve, the latter will make avibrating or dancing movement as long as the steam, gas, or air isadmitted through a L second apertureto the said vessel, or is generatedin the same in a lower degree' or pressure than the valve, in the same[time, according to its diameter, permits the steam,gas, or air toescape. If the valve is opened, the tension in the vessel fallsimmediately to a cer- 25. tain degree, which causes the valve to closeagain, and to remain so for a short time, till the tension is againsufficiently increased by new admitted or generated steam, gas, or airto lift the valve. This principle is practically confirmed by alldancing safety-valves and pot-lids. It will be seen that this samevibratory or dancing motion of the valve will be produced if the valveis able to admit more steam, air, or gas into avessel than in thesame I3 5 time is escaping through another aperture out of the vesseL- I p Inthe accompanying drawings, Figure 1 is 'a' section of the apparatushaving the bell or gong arranged at the side. Fig. 2 is a section thebell or gong ar ranged around the vessel. Fig. 3 is an outside elevationof the apparatus shown in Fig. 2. Fig. 4 shows a section of the upperend a of an apparatus with part of the bell, with which the pressure isalh is the of the vessel 0, supported bya suitable arm, h.

In Figs. 2 and 3 the bell h surrounds the vessel 0, being attached tothe same near its upper end or neck.

In Fig. 1 the valve a is attached to the shaft of the clapper e,oscillating on its pivot t, and communicating the vibrations of thevalve a to the bell h.

In Fig. 2 the valve on is provided .with an internal projection or neck,,d, acting asan untight piston-that is to say, the narrow space betweenthe neck (Z and the surrounding aperture of the'vessel 0 causes thesteam to escape more slowly, and increases in this way the lengthof thelift of the valve a and of the stroke of the clapper e. In order thatthe movement of g the valve amay not become too slow at the end of thelift, the end of the shaft of the clapper e is made to surround the lugsof the pivot z, and is provided with a spring, f, pressing at the propertime against the vessel a, closing thereby the valve a by the action ofthis spring f, as" shown in Fig. 3.

In Fig. 4 the shaft of the clappere does not oscillate, but forms aspring attached to the valve a. Theclapper e strikes the bell h when thevalve 64 is closing.

' 7 Whensteam is used in the apparatus, a small outlet -hole, 9, Figs. 1and '2, must be provided in the vessel 0 for the condensed water.

What I claim as my invention, and desire to secure byLetters Patent, is

1. In a bell-ringing apparatus actuated by steam, gas, or air, thecombination of the vessel 0 with the admitting-pipe b andoutwardly-opening valve a, larger in diameter than the pipe 6, andsecured to the shaft of the clapper, the clapper e, secured to a shaftos-- cillating on a bolt, 1;, and the bell h, substantially as and forthe purpose described. a

2. In a bell-ringing apparatus actuated by steam; gas, or air, thecombination of the vessel c, admitting-pipe b, and outwardly-openingvalve a, provided with a neck, d, secured to the shaft of the clapper e,oscillating around Inwitness whereof I have hereunto signed the pivot i,the spring f at the end. of said my name in the presence of twosubscribing shaft, and the bell h, arranged to operate as Witnesses. andfor the purpose set forth.

5 3. In a bell-ringing apparatus actuated by ROBERT LATOWSKI.

steam, gas, or air, the combination of the vessel c, outwardly-openingvalve a, secured to Witnesses: 7 the shaft, or its equivalent, of theclapper, the FRIEDRICH HENsoKLER, s ring forming the shaft of theclapper e, and v HEINRICH KRUMSIEG'.
